Hello,
I am a beginner in using GMF. I want to understand and maintain a system, which is few years old . I want to use
and rebuild it in eclipse Oxygen. Since gmf tooling is no longer shipped with eclipse i downlaoded it from there
updatesite http://download.eclipse.org/modeling/gmp/gmf-tooling/updates/releases/. But when i try to generate the
gmfgen model i get the error below.
A similar error is also described in the previous post, but the user uses Papyrus. I Thing the guys of payrus have theire own
workaround. For now i am using Neon to learn gmf(tooling). Is there a way to use it with oxygen? Am i doing something wrong?

thanks in advance

Albrecht

Encountering same problem with Oxygen 3 and GMF 3.0.1. Tried adding M2M runtime libraries to the classpath. Still no use. Any suggestions?

To my knowledge, GMF Tooling is not maintained anymore. I'm not even sure anyone from the project is following this forum. The only suggestion I can give you is to keep an older version of Eclipse (pre-Oxygen) around for when you need to launch a GMF Tooling generation, even if you use a more recent Eclipse for the main development. The version of Eclipse (and the required dependencies) used to run the code generation phase does not need to be the version you use to develop the rest of the code, or the target version where the result application will be executed.
